Thunderstorms, hail slow Oklahoma tornado cleanup

OKLAHOMA CITY - A band of thunderstorms is battering the Oklahoma City area and slowing cleanup operations in the southern suburb where a tornado killed 24 people and destroyed thousands of homes earlier this week.

The National Weather Service said Thursday that the storms are producing hail, heavy rain and high winds. A flash flood warning is also in effect for some areas.

The Weather Service says more severe storms are forecast for late afternoon and at night. It says tornados are a possibility.

The suburb of Moore was hit by a powerful twister Monday that shattered whole neighborhoods and hit two elementary schools. Ten children were among the dead.
